Justice For All , if you keep thinking like that, then you surely won't go anywhere.
Half a month, with +1 week since you've wrote that post, is nearly nothing if your very own mind is blocking you along with your fear of failure.
Think positive, my friend, it is better to die trying than to never have tried. I'm not sure if this applies to you, but even if you fail in everything, you can try again next year. Or maybe you will fail some tests and pass others - that is already halfway done! Just do your best, and forget the rest!
No one would have ever imagined that Einstein would become what he became, yet, he's now part of History; thus, immortal.
Clean your mind, relax, and focus on giving your best, regardless of the result. If you're studying while being nervous or unwell, then most of what you study/read/see won't really get stuck in your mind...
And there are some mind tricks you can always use, like recording everything you need to know/study, and constantly hearing it instead of reading it, even during your sleep. Actually, especially during your sleep, because, as you probably know, while you sleep, your subconscious is fully active, and the same way 'it' transmits information to your organism - like making you dream and fart while you sleep (lol) - 'it' also captures information.
This might seem silly, but I actually did this on my final year of Law because I was working part-time, and also suffered a huge personal loss. I recorded my notes of Constitutional Law 2 and Criminal Law 2 because those two were the 'monsters' that actually worried me. And I now regret not doing that before. So I started listening to my own voice through my mp3, whenever I could, at work, driving, at home, whenever and wherever I could, including falling asleep while listening to my own voice
And when the time came, I passed both of them with a fair ease. It's been 11 years now since I graduated, but I remember reading my notes on the nights before both exams, and as I read my notes, I felt like the knowledge was coming out of my brain and that everything was already stuck in my mind... It was one of the most odd experiences I've ever felt in my whole life, and even during the exams, I actually felt relaxed and confident.
No matter how you feel, remember to always keep your hopes high, because if you convince yourself that you are going to fail, then that is halfway into a complete failure; but if you focus and convince yourself that you will succeed, then your chances of actually succeeding are much higher! It's just like sexual dysfunction, in some cases, the men who can't get it up, can't get it up because they're already convinced that they can't get it up, and because they fear they won't please their companion...So just relax, focus on the present moment, and let things happen.
Good luck man! You are one of the most bright individuals I've seen on these forums, and I'm not talking about the stuff you copy paste, I'm talking about the way you think, the way you rationalize certain myths and uncertain matters, you're a smart and intelligent guy, so just chill out and do what you gotta do! Don't let the fear of failure get to you, be strong and be persuasive to your own self.
